environment this product may cause radio
interference in which case the user may be
required to take adequate measures.
This equipment has been tested and found to
comply with the limits for a Class A digital
device, pursuant to Part 15 of the FCC Rules.
These limits are designed to provide
reasonable protection against harmful
interference when the equipment is operated
in a commercial environment. This
equipment generates, uses, and can radiate
radio frequency energy and, if not installed
and used in accordance with the instruction
manual, may cause harmful interference to
radio communications. Operation of this
equipment in a residential area is likely to
cause harmful interference in which case the
